Title: Sheet item handling apparatus
IPC: B07C3/06
Filed: 1960-12-07
Abstract: 926,248. Record sorting machines. BURROUGHS CORPORATION. Dec. 7, 1960 [Dec. 7, 1959], No. 42173/60. Class 106 (1). In a sorting machine for thin records such as cheques, sorting channels are defined by two sets of flexible metal blades UV70 and LV70, Fig. 4, which guide the upper and lower sides of the records, feeding means 76, 78 engaging the central portion of the record between the sets of blades. The upper set of blades is attached to a hinged cover 48 which can be raised to the dotted line position to free jammed records. Both sets of blades are similarly operated at the entrance end by flat magnetic coils as described in Specification 881,016 and at the receiving pockets the ends of corresponding ones in each set are formed to turn the records into the pockets as in Specification 893,743. The cover 48 is supported on a bracket 106 for rotation about a horizontal spindle 100 and movement of this bracket through link 132 lifts an auxiliary closure member. Counterweights are provided with the cover. The records are gripped during their passage through the machine between feed belts 80, Fig. 5, and fixed rollers 76. The belts are pressed against the rollers 76 by movable rollers 78. When the cover is lifted, cams on the spindle 100 act through levers 182 and 162 to displace a cam bar 148. This withdraws all the rollers 78 from engagement with the belts 80 and allows the records to be withdrawn. Each roller 76, Fig. 7, has a centrifugal speed-sensitive device consisting of weighted levers 252 which respond to the stopping of the roller to open a switch 260 in the circuit of the driving motor. A jam of records thereby causes the machine to stop. Full-pocket switches may also be provided to stop the machine when any receiving pocket becomes full. Specifications 909,982, 921,637 and 926,247 also are referred to.

Title: Improvements in or relating to wire supply apparatus
IPC: B65H51/20
Filed: 1966-09-23
Abstract: 1,112,738. Accumulating filamentary, material. NATIONAL-STANDARD CO. 23 Sept. 1966 [26 Nov., 1965], No. 42691/66. Heading D1F. [Also in Division B3] A wire i.e. filamentary material, accumulator comprises a pair of panels defining an upwardly open space for receiving wire in an elongated loop, a partition member movable in the space for adjusting the width of the loop and a motor for drawing the wire from a supply source, the motor being stopped by the opening of a normally-closed switch when there is a predetermined maximum amount of wire in the accumulator. Wire W is drawn from a reel by a grooved wheel 14, driven by a motor 16, to pass therefrom to a wire accumulator 6 and thence to a spring coiling machine which draws the wire intermittently from the accumulator. The accumulator 6 comprises side panels spaced by end members 38, 39 and a partition 40, adjustable along slots 34, 36 in the side panels and locked in position by bolts 42. The front side panel may be of clear plastic. A tubular wire guide 52 is mounted on the partition 40. Switch contacts 55, 56, 57, 58 are engaged by the wire loop. If there is insufficient wire in the accumulator the loop lifts the contact 55 to open a switch 66 which stops the motor of the spring coiling machine. If the loop reaches a maximum predetermined amount the contact 58 opens a switch to stop the motor 16. Engagement of the contacts 56, 57 by the loop causes the motor 16 to run at a slower speed than when the contacts 56, 57 are not engaged by the loop. The speed of the motor 16 is adjustable manually. Contacts 56, 57 may be substituted by a single switch.

Abstract: 1,184,907. Rotary cultivators. C. VAN DER LELY N.V. 19 Sept., 1967 [13 Oct., 1966], No. 42708/67. Heading A1B. A soil cultivating implement comprises soil working members 10 which are carried on a shaft 4 which is in driving connection with transmitting mechanism which causes the shaft 4 to rotate in a direction opposite to direction B so that the members 10 move through the ground in a direction opposite to the intended direction of travel A of the implement. A hood (16), Fig. 1 (not shown), partly surrounds shaft 4 and members 10 and is connected to a plurality of spaced resilient rods 17 which extend approximately concentrically around the axis of shaft 4. Soil which is dug up by members 10 is separated into two layers by rods 17, fine soil passing through the rods. The transmitting mechanism is such that the shaft 4 may also be rotated in the direction B. Members 10 are pivotally mounted and automatically assume suitable working positions for both directions of shaft rotation. In a modification, Fig. 5 (not shown), the cutting edges of blades (39) and bodies of soil working members (38) do not extend radially of shaft 4 so that the members displace soil in either direction of rotation of shaft 4. In a further modification, Fig. 6, soil working members 40 are unbolted and remounted when the direction of rotation of shaft 4 is reversed.

Title: Catalytic cracking of hydrocarbons
IPC: B01J29/80
Filed: 1971-09-22
Abstract: 1351035 Catalytic cracking of hydrocarbons MOBIL OIL CO 22 Sept 1971 [6 Oct 1970] 44222/71 Heading C5E [Also in Division B1] Hydrocarbon oils are cracked using a catalyst comprising both a crystalline aluminosilicate having a pore size greater than 7Š and a crystalline aluminosilicate of the ZSM-5 type. The two types of aluminosilicate can be disposed in a catalyst bed either in separate catalyst particles or both in the same particle. The catalyst particles can be formed into beads or extrudates using a porous matrix such as clay or silica-alumina. The ZSM-5 type aluminosilicates have approximately elliptical pores with a minor axis of about 5À5Š and a major axis of 6-9Š and can be a ZSM-8 aluminosilicate. The aluminosilicate of pore size greater than 7Š can be of the X, Y or L type such as a rare-earth metal exchanged faujasite. The hydrocarbon oil can be gas oil, residual oil, cycle stock or a product of the destructive hydrogenation of coal, tar, pitch or asphalt. In examples gas oils are cracked to products comprising gasoline together with propylene and butylenes, which are subsequently alkylated with co-produced isobutane and added isobutane to produce additional gasoline. The use of catalysts comprising zeolite Y exchanged with rare earth metals together with the hydrogen or rare earth exchanged forms of ZSM-5 is compared with the use of a mixture of rareearth exchanged zeolite Y and a 5Š erconite.

Abstract: 1,211,128. Inking apparatus. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE. A.G. 18 Sept., 1968 [28 Sept., 1967], No. 44303/68. Heading B6C. In a multi-colour rotary printing press whenever inking rollers 6, Fig. 2, applying one colour to a forme 2 are lifted during their passage over another forme which prints a second colour, such lifting is effected by a cam 17, Fig. 1, engaging a control roller 16 on a lever 14 pivoted at 15 and connected by a link 12 to a lever 9 carrying one of the rollers 6, the pivot 15 comprising an eccentric pin on a shaft which can be rotated by a handle 28 to adjust the operative position of the roller 6 relative to the forme. Springs 34 extending between pins 11 on pairs of levers 9 associated with each distributing roller 7 maintain the rollers 6, 16 in contact with the forme and cam respectively. Each lever 9 is pivoted about the shaft 10 of a distributing roller 7 contacting two of the rollers 6, and each inking roller 6 is journalled eccentrically in a bush 8 on its lever whereby adjustment of the roller 6 relative to the roller 7 can be effected by rotating the bush. A second control roller 18 is provided on each lever 14 in alignment with a cam 19 which, when printing has been completed, can be rotated by a lever 20 so that high parts thereon engage the rollers 18 and lift all the inking rollers to inoperative position. The machine can be adjusted to print in one colour from all the formes and for this purpose, the control cam 17 is moved axially out of the path of control roller 16. This is effected by means of a disc 23 rotatably mounted on the end of the printing cylinder 1 and having threaded engagement at 22 with the hub of cam 17. With cam 17 inoperative, cam 19 is rotated so that low parts thereof corresponding to the low parts of cam 17 engage the control rollers 18 so that all the inking rollers 6 remain in operative position.

Title: Preparation of phosphatidylethanolamine
Inventor: WORK ELIZABETH
IPC: C07F9/10
Filed: 1965-10-25
Abstract: Phosphatidylethanolamine is obtained by growing a lysie-requiring mutant of a Gramnegative species of bacterium in a sub-optimal concentration of lysine, obtaining a cell-free liquid from the resulting culture, precipitating a complex of phospholipid with protein-lipopolysaccharide from the cell-free liquid by dissolving a polar substantially water-immiscible halogenated hydrocarbon in the cell-free liquid, separating the precipitated material, and separating phosphatidylethanolamine from the precipitated material. The preferred Gramnegative species is Escherichia coli which is grown in a sub-optimal concentration of lysine under conditions such that diamino-pimelic acid accumulates in the culture medium.  The lysine concentration may vary from 20 to 500 mg./litre and the mutant is preferably grown under conditions of high aeration for from 16 to 48 hours at 25 DEG  to 40 DEG  C., the pH of the culture medium being suitably between 5 and 8.  The lysine may be added per se or in the form of a salt, e.g. the hydrochloride, or in the form of a lysine-containing material, e.g. cornsteep liquor.  The cell liquor may be obtained from the culture by centrifugation and then freed from bacteria by membrane filtration.  The polar halogenated hydrocarbon may be chloroform, trichloroethylene or methylene dichloride and the precipitated complex is preferably separated by centrifugation.  The phosphatidyl ethanolamine may be separated from the precipitated complex by treatment with C1-C5 alkanols, e.g. methanol or tertiary amyl alcohol, bile salts or synthetic detergents, aqueous acetone or aqueous ether, and may be purified by precipitation from benzene with acetone or by absorption or chromatography on silicic acid or diethylaminoethyl cellulose.  In an example chloroform is used to precipitate the complex and the phosphatidylethanolamine is separated by treating the freeze-dried complex with methanol at 60 DEG  C.
